摘　　要：针对倾斜无人机影像在三维重建与大比例尺测绘产品生产中的精度难以满足问题,本文首先对连接点进行全局抽稀与局部抽稀相结合的方式对稀少控制点进行补充,然后进行高精度GPS辅助区域网平差,最后利用倾斜无人机影像进行三维重建并进行精度分析。结果表明,在生成的三维模型上编辑生成1∶500地形图的方法满足1∶500地形图成图精度要求。Aiming at the problem that the precision of tilted UAV image in large-scale surveying and mapping product production is difficult to meet.Firstly,this paper supplements the sparse control points by combining global thinning with local thinning,then carries out high-precision GPS-assisted regional network adjustment,and finally uses the tilted UAV image for accuracy analysis.The results show that the method of editing and generating 1∶500 topographic map on the generated three-dimensional model meets the requirement of mapping accuracy of 1∶500 topographic map.
